My Ph is around 6.8-7.0 according to LFS and my Aquarium Pharmaceuticals test kit. My Hagen kit says 7.6. I have been doing two 15-20% water changes daily since I put the Angels in, there is also 6 Head and Tail lights, one red eye, 15+/- Cardinal Tetras, 6 Serpae tetras, 4 Ottos, and one Cory. Nothing else seems to be affected. I haven't done a water change yet today. I have checked everything, I even changed my Quick Filter cartridge last night.
I think the Rams just came sick, and now they are dying. I hope the antibiotic helps, I had also been doing a 2 gallon change on the ten gallon tank once a day. But now that I added the antibiotic last night, I haven't done a change on it.
I use StressCoat during changes. Unless there is something new in the tap water.....
Thanks for your replies.
